CMP-5 hydrochloride is a potent and selective PRMT5 inhibitor, while displays no activity against PRMT1/4/7 enzymes. It selectively blocks S2Me-H4R3 by inhibiting PRMT5 methyltransferase activity on histone preparations.
CMP3a is a NEK2 kinase inhibitor. CMP3a efficiently attenuated GBM growth in a mouse model and exhibited a synergistic effect with radiotherapy. Targeting NEK2 attenuates glioblastoma growth and radioresistance by destabilizing histone methyltransferase E
CMP98, a proteolysis targeting chimera (PROTAC), exhibits a lack of VHL degradation efficacy. It can function as a negative control compound in comparison to CM11. CMP98 comprises two von Hippel-Lindau ligands operating within their active domains.
Cytarabine 5′-monophosphate (ara-CMP), an active metabolite of the nucleoside analog cytarabine formed by deoxycytidine kinase, is incorporated into DNA by DNA polymerase α, significantly slowing DNA synthesis. It inhibits nuclear and mitochondrial DNA replication in S. cerevisiae at 15 mM and improves survival in an L1210 murine leukemia model at 3.5-75.1 mg kg.
Cytidine 3'-monophosphate, a ribonucleotide, results from the hydrolysis of cytidine 2’,3’-cyclic monophosphate via RNase—a process that cytidine 3'-monophosphate itself inhibits. Additionally, it can be dephosphorylated to cytidine by 3’-nucleotidase.
